LCA20 Intelligent Strain Gauge Load Cell Amplifier |
Description
The LCA20 intelligent strain gauge amplifier can be used for multiple or single load cell applications, and offers very easy one pass calibration and fast set-up. It also provides both 4 to 20mA and 0 to10 volt analogue outputs from any standard strain gauge input, and the transducer excitation voltage of 5 volts @160mA will power up to ten 350ohm bridges connected in parallel. Auto Tare and Peak Hold (if set) on the analogue output are operated via volt free contact closures, and output options include relay set points programmed in engineering units, with in flight compensation and hysteresis settings are available for control or alarm purposes. The LCA20 features RS232 and RS485 digital data output for communications and printing, and firmware now supports Mantrabus 1&2, Mantra ASCII 2 and Modbus RTU. Printing can be actioned by a contact closure, and the printer can print the current live value, with header message, engineering units, auto incrementing batch number and in real time if required (using a printer with time/date facility). The LCA20 also enables selection of device parameters via a PC or keypad rather than using the traditional on-PCB switches. |
